This invention relates to warp beams and has for its principal object the provision of a warp beam or roll of simple and durable construction which may be driven at high speed without damage to the beam or to the yarn wound thereon.' Other objects are to provide.

a segmental wooden beam Which may beI readily assembled and conveniently turned down to proper diameter; to provide improved means for so connecting the beam cylinder to its heads as to insure rigidity of the as.

Fig. 1 is a broken longitudinal section of the improved warp beam;

Fig. 1a is a detail similar to Fig. 1 showing a modification;

-Fig. 2 is an end view of the same;

Fig. 3 is an enlarged transverse section taken on the line 3--3 of Fig. 1;

Fig. 4 is an enlarged transverse Section through the warp roll, taken on the line 4-4 of Fig. 1;

Fig. 5 is -a fragmentary longitudinal section through one end of the beam, taken on the line 5-5 of Fig. 4; and

Fig. 6is a fragmentary developed section of the abutment joint between the cylinder and head, taken on the cylindrical surface 66 of Fig. 5.

The warp-beam comprises in general a cyl- 'inder or barrel 7 preferably of built-up construction and consisting of interlocking longitudinal wooden staves, some of which are,

secured upon interior supports, a pair of beam heads 8 of wood or other suitable material and having a grooved peripheralmetal belt seat 9, and a beam shaft 10 passing axially through the heads and stave supports' and tensioned by nuts 11 on threadedQ ends of the shaft 10 adapted 'to clamp the heads tightly against ltensionfnuts is relieved. The other cooperatthe barrel ends. As shown in Fig.f 1, the nuts 11 may be vformed as sleeves entering a central bore in and bearing for heads 9 in some cases, the nuts 11a may be cXterior'to the heads, which are then bored to fit the shaft l0 (Fig. 55 la). A metal reinforcing plate 0r disc 12, preferably let into the outer faces of each respective beam head and extending outwardly to overlie the respective ends of the roll 7, is preferably provided to furnish a firm and even bearing surface for the nut and to assist in drigidly clamping the heads to the barrel en s.

The barrel 7` is Apreferably constructed by mounting four similar staves 13 upon the respective ends of a series of crossed supporting members lef and 15, which may consist of stout wooden blocks rigidly secured face to face and at right angles to each other by gluing and by nails 16, or by other suitable fastening means. Bolts 17 and 18, having their heads received within counte'rbored openings in the staves and bearing upon metal washers 19 and 20, respectively, may be employedto fasten the staves upon the ends of the respective supporting blocks 14 and 15, these blocks having transverse openings 21 at the ends of the bolts to permit nuts 22 to be threaded thereon. The staves 13 preferably have longitudinal grooves in their beveled. edges, adapted to receive complemental tenons of four other staves 23 which are driven endwise between the staves 13 to provide a compact and closely united segmental cylinder. The outside of the assembled cylinder may then be turned down to a smooth surface of the desired diameter and the counterbores inthe staves may be plugged by bungs 24. y

The number of the crossed supporting menibers used depends upon the length of the beam, oneV of the supports preferably being disposed vnear each end of the barrel in proximity to the beam head, in order that one block of each end member may form part of a clutch which is adapted rigidly to connect the head to the barrel so that relative rotation thereof is eectively restrained and whereby torsion strain upon the beam shaft and its ing element of the clutch preferably comprises a pair of metal flanges of angle plates 25 spaced in parallel relation, one on each side of the beam shaft, and secured to the inner face of each beam head, as by the 5 bolts 26, 26 which pass through the head and the lother flange ot' the angle plates25 and may also serve to attach the reinforcing plate 12 to the outer face thereof,.as best shown in Fig. The plates 25 are so positioned that their upstanding flanges constitute jaws to receive and mate with one of the blocks of the end roll supporting member, for example the block 15, Figs. 4 and 5. The supporting block being rigidly fixed to the barrel 7, the latter 15 is accordingly so connected by the clutch to under braking restraint.

In order-further to provide means to preventsuch relative movement and to ensure against pinching or breaking of the yarn at said joint, the meeting surfaces of the barrel vend and beam head may be in annular grooves 27 and depressed below the surfaces` 81L of the heads and so formed as to present in any rotative sense coinpleinental interengaging portions, preferably so ar- 30 ranged that the end of each stave is received within the inner face 8a of the head and iiiterlocked with the head at spaced intervals, as indicated at 27,27a (Figs. 5 and -6). The# abut-ting faces may accordingly 3; have interfitting radial ribs and grooves or other interlocking or frictionally engaging elements adapted to prevent or restrain relative rotational movement; but the provision of rounded, relatively shallow radial grooves ,40 and contiguous cooperating ribs, which in developed section constitute complementary.

sinusoidal or other cam faces (Fig. 6) is recommended. Such 4a construction permits a slight relative turning movement without damaging-the interfitting portions and, in

case such movement occurs,the result is not `(lisadvantageous since it resolves into longitudinalinovement and servesv to increase the tension on shaft 10 andtherefore support the 5o lshaft further against flexing strains and holds the' parts more rigidly together.

Locking means adapted to prevent turning of the tension nuts 11 are preferably pro vided, and may comprise. metal locking-rings or washei's 28 having one or more interior lugs 29 adapted to'fit between the teeth 30 ofthe castellated hub of the nuts 11, when the nutsfre sufficiently tightened by means of a wrench applied Ito their polygonal heads.

While the nuts 11 are being set up, the ring lugs may be received in annular grooves 31 of the nut hubs; and when the nut is to be locked,

S the rings may be secured by means of pins 32 Fig. 1` or 32a Fig. la, which are carried by the reinforcing plates 12 andwhich extend through 'appropriate apertures in the locking rings, cotter pins being provided to prevent casual dislodgment of the rings. As shown in Fig. 1. these pins may be the projecting ends of' bolts 32 in bores in the heads 8 having threaded ends screwed into tapped holes in plate 12, and extending outwardly through the boi'es in plate 28, which are not tapped.

A warp beam constructed as above described and herein claimed is simple and economical to manufacture. easyto assemble and to take apart in case repairs should become necessary, and particularly strong and durable in use without having excessive weight, as well as useful to attain the several objects of this invention mentioned above; the particular details of construction may be varied within the definitions of the .claims as desired `without departing from the invention.
